[Brewer89] R. Brewer Design Tips for EMI Shielding., Machine
Design, (March 23, 1989):85--88. [This paper explains the difficulty in
deciding whether enough shielding has been used and mentions that
ElectroMagnetic Interference (EMI) was suspected in Army Blackhawk
helicopter crashes because the Navy version has more shielding and fewer
crashes. A graph is used to show shielding effectiveness versus frequency
for electrical and magnetic fields using two different materials.]
